Wilson Kneebone, 49, pleaded guilty to aggravated assault by vehicle and driving under suspension before Northampton County Judge Jennifer Sletvold, according to court documents.

Sentencing was deferred so Kneebone could undergo evaluation.

Kneebone was heading east Nov. 8 on Lehigh Drive in Easton when he struck 18-year-old Aubrey Baumbach with his Jeep Grand Cherokee as she and fellow members of the Easton college's rowing team left the boathouse.

According to a lawsuit filed by her family over the crash, Baumbach was thrown 20 feet from the collision.

Kneebone did not stop at the scene, but police were able to link him to the crash from surveillance footage and eyewitness statements. When police went to his home two days later, they found Kneebone's Jeep had front-end damage, according to court documents. Kneebone quickly admitted to striking Baumbach, police said.

At the time of the crash, Kneebone's license was revoked for a 2012 drunken-driving conviction -- his fourth since the 1980s. Authorities could not determine whether he was drunk at the time of the crash because of the amount of time between the crash and his arrest.

Baumbach suffered catastrophic brain injuries from the accident, according to her family's lawsuit against Lafayette College.

The suit claims the school failed to provide transportation to the boathouse, a safe passageway to get there or enough parking for students who drove there. On the day of the crash, a car was blocking the adjacent parking lot, so the car in which Baumbach was riding had to park farther away, the suit says.

In December, she was transferred from St. Luke's University Hospital in Fountain Hill to a Massachusetts hospital, where she could be closer to her family.
